I totally agree, the ladders were definitely in a "good enough" state when we finished but I'd love to go back and fix them. In the future, you should be able to walk across the top without falling down and getting to the bottom of the ladder should immediately release you. But it's a gamejam and you can only do so much with your time and it was way more important to get some of the polish in. Here's what the game looked like a couple days ago: http://i.imgur.com/suZT2uF.png
